Answer: Chinese cities included prosperous merchants and vibrant trade.
Explanation:
From the text it is seen that there was a lot of trade going on in the city. Everywhere one goes there are hundreds of shops. This means that trade must have been very vibrant.
Cities with vibrant trade make for trading hubs that will attract people from far and wide. This would therefore give merchants the opportunity to become very successful and prosperous from selling their wares.

In 2016, California passed 900 new laws. In 2015, there were 930 new laws. About 900 laws will be passed in 2017 as well.
So, if you are counting only 2015, and 2016, there were approximately 1830 new laws in those past two years only in California. Not all of them are good, not all of them made people happy, but it is not the people who decide about this, unfortunately (or perhaps fortunately?).
